LUMBER cAJaRIEa.

To all it concern: H Be-it. known that I, CARL F. GERflINonR,'a citizenof the United States,'residing in Dallas, in the county of Polk andState of Oregon, have invented certain new and useful Improvements inLumber Carriers, of which the following is a specification. Thisinvention relates to lumber carriers of the kind in which provision ismade for raising a load of lumber, for carrying it to its destination,and for depositing it there.

While my improvements are especially intended for the purposesalreadymentioned they may be embodied in trucks of carriers for raisingand conveying loads ofvarious .kinds', but as my improvements areespecially intended for carryin will, for the most part, herea ter bereferred to forthat purpose.

According to this'invention, I provide a for causing lifting devices toengage the load and raise it sothat it can be properly transported.The'ilriving mechanism is such that ,the truck may be driven eitherforwards or backwards, and automatic devices are employed for stoppingthe elevating mechanlsm and for releasing the load when desired.Automatic devices are also employed for stopping the descent of theelevating devices when lowered. r

Instead of employing ropes or cables for operating the lifting shoes I'employ shafts and gearing ofv substantial and rellableconstructionandwhich are controlled by clutch levers.

. The main frame of the truck or carrier "COIIIPIISGS a platform Ahaving front arms or brackets a and rear arms or brackets-a whichproject laterally sideways from the truck. At the front of the truckthere are bars a, a and at, as shown. in Fig; 1. It

will be observed by reference to Fig. 3 that the frame as a whole is ofa general U shape sojthat it maybe drawn over'a load support: ed by atable or carrier X. The frontflwheels B, which are the steermg wheels,arejournaled in U-shaped frames C, carrying posts -D, supported insuitable brackets E and having collars d supporting springs F on whichthe frame arms a of the p)latform rest. The u per ends of the postscarry'crank arms G. One of the posts D has an arm 9 which is connectedby links 9, g with the steering mechanism H. It is obvious from aninspection of Fig. 1 that by operating the wheel H the .truck may beconveniently steered.

The rear wheels J are journaled: in U- shaped frames j, carrying posts Jextending through brackets -j' and having collars 1 c supporting springsK on which rest the rear arms a of the platform.

connected by-a link j The rear wheels carry bevel gears Z withwhichmeshbevel pinions Z on shafts L having universal joints at Z and anextensible connection at Z. 1

Each shaft L, as shown, is made in two and enters a sleeve Z the part?)which also enters the sleeve Z and is joined. at Z to the part 4 whichlatter part carries at its upper end a pinion Z. The several partsof theshafts L are supported and guided by the frame parts a. By thisconstruction provi-'- 'SlOIl is made for allowing the truck to travofthe truck above the platform, and mount-' 'ed to-turn in suitablebearings thereon. The shaft N carries spur wheels 0, 0' adapted toengage similar wheels P, P, on the shaft Q, carrying a beveled pinion Radapted to engage either of the cone gears r, 1" on the shaft Sdriven'by the engine T. The gear structed and operated in the usual wayand need not be further described. The shaft N carries brake mechanism Nwhich may also be of ordinary construction and need not be furtherdescribed.

The cone gears 7', 1- are associated with clutches r r These clutchesare of Well known, construction, being of the cone type, and are forthe,purpose of connecting either one of the pinions r, 1- with thedriving shaft S so that the shaft N may be driven in either direction topropel the truck forwards or backwards. The clutches are operated andcontrolled' by a lever T which operates levers t, 25 connected by a linkt The lever T has detent mechanism operating in a toothed segment t Thelever may be set to hold the clutch mechanism in neutral position sothat there is no driving connection between the shaft S and the shaft N,or it maybe operated when pushed forward to connect the shaft S with theshaft N to advance the vehicle. When the lever T is pushed backwards toits full extent, the connections are proper for driving the trunkbackwards.

The shaft- S carries at its rear end cone gears v, c which engage bevelgears u, u, on shafts U, U. These shafts U, U are parts of mechanism foroperating the loadlifting devices.

The gears 11, o are associated with cone clutches V, V on the shaft Sand these clutches are associated with shifting devices whereby theshafts U, U may be driven in either direction. As shown, the appropriateclutch mechanism is engaged by levers 'w, '11: connected by a link 102.The lever 20 is attached to a horizontal rod 10 to which the operatinglever W is secured. The lever \V hearings on the platform A. The shaftsZ carry worm wheels Z which engage worms Z on the shafts U, U. By thismechanism, when the shafts U, U are operatively connected with theshafts S,the rack bars may be raised and lowered, the direction ofmovement being controlled by the clutch mechanism. By Operating thelever TV the lowering devices may be raised or lowered as desired.lowered the lever is held by the operator.

"TVhen thershafts U, U are disconnected is provided with a detentengaglng a segment TV having a single notch as shown.- Vhen the detentengages the notch the lever is in a neutral position, and then'theshafts U, U are not operatively connected with the shaft S. The lever wis pivoted at 10*. The rod 20 carries arms 10 which extend downwardlyand 'rearwardly in the truck frame and are connected at their lower endsby a rod 10. When the arms to are swung up wards or" downwards theyoperate the clutch mechanism in the manner shown. The shaft w carries anarm w which is operated. by devices herelnafter described to automati-'cally operate the clutch mechanism at cer- Y suspended from rack bars Yby linksy',

from the shaft S the detent may be made to engage the segment W to holdthe mechanism in neutral position.

The arm 20 of the rod 10 is adapted to be engaged by a lug 108 on one ofthe rack bars.

VVhen' being raised or Vhen the rack bars are loweredto the full loweredto their full extent they are withdrawn towards the sides of the .truckso as to leave a clear space for the truck to pass over a load andget-into position to lift the load. The shoes are held in the position Ishown in Fig. 7 by the springs 3 3 the links g being held against theframe parts of, a Vhen the rack bars are operated to raise the shoes, inthe manner shown in Fig. 6, the springs yield and the links y. y assumea vertical position, as shown. At this time the shoes are under theload, as indicated in Fig. 5, and the load with its supportX is clear ofthe ground. The truck may then be propelled to carry the load to itsdestination.

Vhen the load has reached its destination,

the lever "V may be operated to so clutch the shafts U, U to the shaft Sthat the rack bars will be lowered to deposit the load. In order thatshocks may be avoided, the lug w is provided to engage the clutchmechanism and disconnect it so that the lowering operation may besuspended at the proper time.

In like manner, when the shoes arebeing raised the clutch mechanism.maybe disconnected by the devices be fore described to suspend the raisingoperation. This .is

. brought about by the top of the load coming in contact with the rod wand swinging the same with the arms '10. This rocks the shaft e or rod*w and through the lever w moves the 'clutch to disconnect .the liftingmechanism from the operating'shaft I It will thus be seen that means isprovided whereby an engine or motor onthe truck may propel it eitherforwards or backwards and i this sameengine maybe employed to operateperience has demonstrated that the' automatic devicesforfstopping thelifting. and lowering mechanism are of great practical importance andthe mechanism whereby the clutches may be controlled manually as well asautomatically are also useful in service.
